Throwable 异常信息转为字符串方便日志记录

public static String errorInfoToString(Throwable e) {
    //try-with-resource语法糖 处理机制
    try(StringWriter sw = new StringWriter();PrintWriter pw = new PrintWriter(sw)){
        e.printStackTrace(pw);
        pw.flush();
        sw.flush();
        return sw.toString();
    }catch (Exception ignored){
        throw new RuntimeException(ignored.getMessage(),ignored);
    }
}
